MacWrite was a WYSIWYG word processor application released along with the first Apple Macintosh systems in 1984. Together with MacPaint, it was one of the two original "killer applications" that propelled the adoption and popularity of the GUI in general, and the Mac in particular.
MacWrite was spun off to Claris, who released a major update in 1989 as MacWrite II. A further series of improvements produced 1993's MacWrite Pro, but further improvements were few and far between. By the mid-1990s, MacWrite was no longer a serious contender in the word processing market, and development ended around 1995.
